There are a few things to keep in mind when using the rephrasing feature:
You can only rephrase one sentence at a time
You need a LanguageTool Premium account to use the rephrasing feature to its full extent
Please check https://time.is. Is your clock more than 2.0 seconds too fast or too slow? This may cause errors when using the rephrasing function.
If you still have problems with this feature, please contact our support team.
